This is about the generative fill tool provided in Photoshop beta version currently.
I tried to add several famous personalities, for example: hollywood actress, bollywood actors etc but no matter what, the AI just doesnt recognize any single of them and rather adds weird distorted images which looks almost like aliens.
The other thing which I would like to mention is that most of the times, if human pictures are added by generative fill, either the face or hands are distorted too much which looks like alien pictures or those are made too much "surface blurred" which doesnt really blend well with the background and surrounding people in the existing photo.
This should be good features to have to be corrected.
